oLINci-irne crooL.-

Application filed August rlhis invention relates to certain new and useful improvements in clinching tools and refers more particularly to a device for clinching nails and the like used in the manl ufacture of boxes and other containers.

Heretofore nails have been merely bent or struck over to obtain the desired clinching edect, but this method has many ob]ections,y one of which is that a nail point thus turned or struck over in a short time will work itself to a position with its point slightly raised. This, of course, is extremely objectionable, as the Apoint of the nail thus exposed continually catches ones clothing and oftentimes causes serious cuts to the erson handling ak container so nailed.

With the above and other objections in mind this invention has as an object t-he provision of means 2o rected back into the work.

Another object of this invention resides in the provision of a tool which is relatively light, which accomplishes its object in a highly satisfactory manner and which is exp 2s tremely simple in design.

Vith the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly dened by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come Within the scope of the claims.

In the accompanying drawing I have ili lustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the 4practical application of the principles thereof, and in which:

Figure 1 is a perspective view of a clinching tool embodying my invention;

Figure 2 is a bottom view of the working end thereof, and

Figure 3 is an end view of my improved tool showing the manner of application.

Referring now more particularly to the accompanying drawing in which like numerals designate like parts throughout the several views, the numeral 5 designates any piece of work, such as a box or other container top to which it is desired to secure a cleat or other means 6 by nails 7. It is desirable that the nails 7 be long enough to by which a nail point is diy e, 1926. serial no. 127,613.

penetrate the work or cover 5 6 with a portion thereof extending therethrough to be turned over so that it forms a posit-ive tie between the two pieces, and to this end l have designed the clinching tool, now about to be described.

The tool proper consists of a body memb-er 8 preferably of round stock, although any other cross-sectional shape will be satisfactory, with one end 9 thereof slightly bent at an angle to the main portion. The bottom of the member at its end 9 is flattened, as at l0, to provide a work engaging face and has a slot ll therein arranged at right angles to the face 10 to form forks 12. The opposite end of the body portion has a rod 13 passed therethrough to form a handle for convenience in manipulating.

'lo apply my improved tool, itV 's placed with the face 10 flat on the work and the nail engaged in the slot l1, see Figure 3. l/Vhile held in this position, the end or point of the nail is struck over one fork l2, directing-the oint of the nail back into the work as shown in dotted lines in Figure 3. The tool is then removed and the looped or bent over nail end is driven into the work, as will be readily evident. y

It will be noted that the flattening of the end 9 is such that the forks 12 are longitudinally tapered` thus providing means vfor forming a small or large loop on'the extended nail end,'depending upon the length of extension of the nail. Y

'What l claim as my invention is:

1. A tool of the character described, comprising a body portion having one end flattened and directed at an angle to the body portion to provide a work engaging face and having a s lot therein to receive a nail extension, and means over which the nail may be struck 'to shape the nail extension into substantially a loop and direct the point thereof back on itself.

2. A tool of the character described, comprising a body portion having `a slot therein adapted to embrace a nail extension, and means over which the nail may be struck to direct its point back upon itself, said means being tapered to` accommodate nail extensions of diderent lengths.

3. A tool of the character described, comprising a body member having a slot thereinto receive a nail extension, said slotted portion of the body member having its under and the cleat l surface substantially Hat and its' upper surface arcuate, andprongs defined by kthe'slot in the body member and providing means over which the nail extension may be.. `Struck 5 to direct its point back upon itself and permit the same to be clinched. y

4. A tool of the characterdescribed, comprising a body member having one end p01'- tion beniJ at an angle thereto, said' end portion being longitudinally slotted and having itsA bottom surface substantially lat and its topy Surface4 arcuatez and the prongs formed by the slotting of said end portion providingmeems over Which a nail may be clinched.

In testimony whereof I affix my signature.
